The Psychosocial Beliefs, Experiences And Expectations Of Children Living With Obesity, Lisa Newson, Nicola Sides, Amineh Rashidi

Research outputs 2022 to 2026

Background: Childhood obesity has been shown to impair psychological health. However, psychological factors are often overlooked in both research evaluations and treatment interventions, and children's perspectives on managing obesity are underexplored. Neglecting psychosocial factors might undermine interventions. This research explored the psychological beliefs, expectations and experiences of children living with obesity (range 7–13) and attending a weight management programme (WMP). Methods: Thirty-four participants (19 females, 15 males, average age 9.5 years) completed a semistructured interview. Recorded interviews were transcribed verbatim and analysed using thematic analysis. Results: Four overarching themes were developed: (1) defining health and self-recognition; (2) external influence; feedback, …

Contextualizing The Neural Vulnerabilities Model Of Obesity, Timothy D. Nelson, Eric Stice

Department of Psychology: Faculty Publications

In recent years, investigators have focused on neural vulnerability factors that increase the risk of unhealthy weight gain, which has provided a useful organizing structure for obesity neuroscience research. However, this framework, and much of the research it has informed, has given limited attention to contextual factors that may interact with key vulnerabilities to impact eating behaviors and weight gain. To fill this gap, we propose a Contextualized Neural Vulnerabilities Model of Obesity, extending the existing theory to more intentionally incorporate contextual factors that are hypothesized to interact with neural vulnerabilities in shaping eating behaviors and weight trajectories. We …

Circadian Misalignment And Childhood Obesity: An Unexplored Target For Intervention And Treatment, Mason Pilling

Student Works

Childhood obesity is a pandemic affecting almost 40 million individuals aged 5-18 globally. Many current interventions are relatively successful at treating childhood obesity, yet the rate of childhood obesity continues to increase from year to year, and current intervention methods are struggling to keep up. Mounting evidence suggests that sleep may be a crucial mechanism for understanding and treating obesity, yet sleep still remains a relatively unexplored target for intervention. Circadian misalignment, a measure of the difference between the body’s preferred sleep timing and actual bed and wake times, has been almost completely ignored in the literature, despite preliminary findings …

Shifting Weight Attitudes? A Look At Stigma And Implicit Bias, Carolyn H. Decicco, Sarah L. Capen-Becerra, Sophie K. Louis

Psychology Presentations

The goal of the current study is to investigate students’ perceptions of controllability and biases against individuals who smoke and individuals who present as ‘overweight’ in the workplace. Participants (N = 69) were randomly assigned to read an article describing either weight-based (n = 35) or smoking-based discrimination in the workplace (n = 34). Participants were tasked with writing open-ended responses to the articles. Participants in the smoking group were more likely to endorse (n = 16; 47.1%) discriminatory workplace practices than those in the weight group (n = 4; 11.4%), who showed more conflicted justification responses (weight n = …

Mobile Health App For Adolescents: Motion Sensor Data And Deep Learning Technique To Examine The Relationship Between Obesity And Walking Patterns, Sungchul Lee, Eunmin Hwang, Yanghee Kim, Fatih Demir, Hyunhwa Lee, Joshua J. Mosher, Eunyoung Jang, Kiho Lim

Nursing Faculty Publications

With the prevalence of obesity in adolescents, and its long-term influence on their overall health, there is a large body of research exploring better ways to reduce the rate of obesity. A traditional way of maintaining an adequate body mass index (BMI), calculated by measuring the weight and height of an individual, is no longer enough, and we are in need of a better health care tool. Therefore, the current research proposes an easier method that offers instant and real-time feedback to the users from the data collected from the motion sensors of a smartphone. The study utilized the mHealth …

A Meta-Analysis Of Associations Between Weight Bias Internalization And Conceptually-Related Correlates: A Step Towards Improving Construct Validity, Kelly A. Romano, Kristin E. Heron, Cassidy M. Sandoval, Lindsay M. Howard, Rachel I. Macintyre

Psychology Faculty Publications

Weight bias internalization (WBI), a process of weight-based self-devaluation, has been associated with adverse mental and physical health. However, there are limitations with the existing conceptualization and operationalization of WBI that raise questions about the implications of this evidence-base. To address these limitations, the present study investigated the construct validity of WBI by conducting a meta-analysis of associations between WBI (as currently operationalized) and conceptually-related correlates. Studies identified through October 2021 that provided zero-order correlations for associations between WBI and conceptually-related constructs were examined. Meta-regression determined whether these associations differed across WBI measures and demographic (age, sex/gender, race, BMI) and …

Research Collection School of Social Sciences

There is a paucity of effective intervention tools for overweight/obese women to assess, guide and monitor their eating behavior. This study aimed to develop a lifestyle intervention tool, assess its acceptability and usefulness, and verify its construct validity in overweight/obese women. The 6P tool (Portion, Proportion, Pleasure, Phase, Physicality, Psychology) was developed and 15 women with a body mass index (BMI) ≥ 25 kg/m2 were interviewed to assess its perceived acceptability and usefulness. Subsequently, the revised 6P tool was tested in 46 women with a BMI ≥ 25 kg/m2. The Three-Factor Eating Questionnaire (TFEQ), International Physical Activity Questionnaire-Short (IPAQ), and …

Learning Of Food Preferences: Mechanisms And Implications For Obesity & Metabolic Diseases, Hans-Rudolf Berthoud, Christopher D. Morrison, Karen Ackroff, Anthony Sclafani

Publications and Research

Omnivores, including rodents and humans, compose their diets from a wide variety of potential foods. Beyond the guidance of a few basic orosensory biases such as attraction to sweet and avoidance of bitter, they have limited innate dietary knowledge and must learn to prefer foods based on their flavors and postoral effects. This review focuses on postoral nutrient sensing and signaling as an essential part of the reward system that shapes preferences for the associated flavors of foods. We discuss the extensive array of sensors in the gastrointestinal system and the vagal pathways conveying information about ingested nutrients to the …

Much Ado About Missingness: A Demonstration Of Full Information Maximum Likelihood Estimation To Address Missingness In Functional Magnetic Resonance Imaging Data, Timothy D. Nelson, Rebecca L. Brock, Sonja Yokum, Cara C. Tomaso, Cary R. Savage, Eric Stice

Department of Psychology: Faculty Publications

The current paper leveraged a large multi-study functional magnetic resonance imaging (fMRI) dataset (N = 363) and a generated missingness paradigm to demonstrate different approaches for handling missing fMRI data under a variety of conditions. The performance of full information maximum likelihood (FIML) estimation, both with and without auxiliary variables, and listwise deletion were compared under different conditions of generated missing data volumes (i.e., 20, 35, and 50%). FIML generally performed better than listwise deletion in replicating results from the full dataset, but differences were small in the absence of auxiliary variables that correlated strongly with fMRI task data. However, …

Sensitray: An Integrated Measuring Device For Monitoring Children’S Mealtime Dietary Intake, Hunter S. Guru, Anthony D. Weng, Santosh Pitla, Dipti Dev

Department of Child, Youth, and Family Studies: Faculty Publications

Childhood nutrition establishes consumption norms that affect an individual’s health over the course of their lives. However, early nutrition interventions to establish such norms are uncommon owing to the various inefficiencies associated with current methods of measuring childhood nutrition. Here, we present an IoT measuring device, called the SensiTray, which accurately tracks mealtime intake in a child-friendly and cost-effective fashion. Principal technologies underlying the SensiTray (including mass-sensing technologies, microcontrollers) are identified and analyzed, along with other design choices. Operation of the SensiTray is explained with special attention given to SensiTray software peripherals and algorithms. Preliminary testing consisted of static and …

Weight-Related Psychological Inflexibility As A Mediator Between Weight Self-Stigma And Health-Related Outcomes, Julie M. Petersen, Carrie Durward, Michael Levin

Psychology Student Research

Weight self-stigma, the internalization of negative societal stereotypes, is a problem amongst populations with high weight. Weight self-stigma is associated with psychological inflexibility and maladaptive health-related behaviors. In this study, we explore how weight-related psychological inflexibility may influence weight self-stigma and health-related outcomes in 79 adults with high weight. Participants were primarily white (92.4%) and female (82.3%), with an average age of 39.56 and average body mass index of 33.78. The present study uses baseline, self-report data from a larger trial. Results indicate that weight self-stigma was negatively correlated with maladaptive eating behaviors, weight, and mental health. Weight-related psychological inflexibility …

Examining The Ecological Validity Of The Power Of Food Scale, Lindsay M. Howard, Kristin E. Heron, Kathryn E. Smith, Ross D. Crosby, Scott G. Engel, Stephen A. Wonderlich, Tyler B. Mason

Psychology Faculty Publications

Purpose

Appetite for palatable foods may impact eating-related behaviors in everyday life. The present study evaluated the real-world predictive validity of the Power of Food Scale (PFS) using ecological momentary assessment (EMA).

Methods

30 women who reported binge eating completed the PFS and related measures. Subsequently, during a 14-day assessment period, participants completed five daily EMA surveys of appetite and binge eating via text message and web.

Results

Results of generalized estimating equations showed that higher PFS scores were associated with higher momentary levels of hunger, eagerness to eat, and urge to eat but were unrelated to fullness, preoccupation with …

Greater Social Cohesion Is Associated With Lower Body Mass Index Among African American Adults, Adolfo G. Cuevas, Ichiro Kawachi, Kasim Ortiz, Mariam Pena, Lorraine R. Reitzel, Lorna H. Mcneill

Publications and Research

Obesity remains a public health issue, especially for Blacks (or African Americans). Obesity is thought to reflect a complex interaction of socioenvironmental, biological, and cognitive factors. Yet, insufficient attention has been given to psychosocial factors like social cohesion within the African American community. Using multivariable linear regression, we examined the association between social cohesion, measured by the Social Cohesion and Trust scale, and body mass index (BMI) with cross-sectional data (n = 1467) from a cohort study (2008–2009). Greater social cohesion was associated with lower BMI (b = -0.88; 95% CI: −1.45, −0.32) in an unadjusted model. The association was …

The Effects Of Childhood Adversity, Juvenile Arrest, And Self-Regulation On Adults With Delinquency Histories, Michelle Ann Rhoden

FIU Electronic Theses and Dissertations

Previous studies reported that childhood adversity has debilitating effects on adult well-being. A high prevalence of youths with delinquency histories experience childhood adversity and are at high risk for lasting negative outcomes. Research identifies that the disruption in self-regulation (SR) development explains the effects of childhood adversity on well-being outcomes.

Using data from Add Health, a national study, this dissertation (1) developed a valid and reliable measure of adult SR deficiency, (2) assessed the mediating effects of adult SR deficiency on the association between childhood adversity (i.e., child maltreatment [CM], violent victimization [VV], and economic hardship [EH]) and adult well-being …

A Randomized Controlled Trial Of Online Acceptance And Commitment Therapy To Improve Diet And Physical Activity Among Adults Who Are Overweight/Obese, Michael E. Levin, Julie M. Petersen, Carrie Durward, Brittany Bingeman, Elizabeth Davis, Cindy Nelson, Shannon Cromwell

Psychology Student Research

Background: Acceptance and commitment therapy (ACT) has shown benefit for improving diet, physical activity, and weight among adults who are overweight and obese. However, research to date in this area has primarily evaluated ACT delivered through in-person interventions, which has more limited access relative to online formats. Purpose: The present study evaluated an online guided self-help program that integrated ACT with nutrition education to improve healthy eating and physical activity. Methods: A sample of 79 adults who were overweight/obese were randomized to receive the 8-week ACT on Health program plus weekly phone coaching or to a waitlist. Results: Participants completed …

A Pilot Randomized Controlled Trial Of Acceptance And Commitment Therapy Guided Self-Help For Overweight And Obese Adults High In Weight Self-Stigma, Sarah Ann Potts, Jennifer Krafft, Michael E. Levin

Psychology Student Research

Weight self-stigma, in which individuals internalize stigmatizing messages about weight, is a prevalent problem that contributes to poor quality of life and health. This pilot randomized controlled trial evaluated acceptance and commitment therapy (ACT) guided self-help using The Diet Trap (Lillis, Dahl, & Weineland, 2014) for 55 overweight/obese adults high in weight self-stigma. Participants were randomized to the ACT self-help book plus phone coaching (GSH-P; n=17), self-help book plus email prompts only (GSH-E; n=20), or a waitlist condition (n=18), with online self-report assessments at baseline and posttreatment (8 weeks later). Participants reported high satisfaction ratings and engagement with the ACT …

Bidirectional Associations Between Obesity And Cognitive Function In Midlife Adults: A Longitudinal Study, Andree Hartanto, Jose C. Yong, Wei Xing Toh

Research Collection School of Social Sciences

The links between obesity and cognition remain equivocal due to a variety of methodological limitations with current research, such as an overreliance on body mass index (BMI) as a measure of obesity, the use of cross-sectional designs, and inadequate specification over the domains of cognitive function to be examined. To address these issues, we used data from the Cognitive Project of the National Survey of Midlife Development in the United States, a large-scale, longitudinal dataset on non-institutionalized midlife adults (N = 2652), which enabled us to examine the long-term bidirectional relations between obesity and two latent factors of cognition—executive function …

Mindsets Of Health And Healthy Eating Intentions, Fanice M. Thomas, Jennifer L. Burnette, Crystal L. Hoyt

Jepson School of Leadership Studies articles, book chapters and other publications

Across two studies, we examined the relation between mindsets of health, expectancy-value and eating intentions. We also explored if relations are stronger for African Americans compared to White Americans. In Study 1, we conducted a correlational study (N= 158) to examine initial relations among constructs. In Study 2, we employed an experimental design (N = 205), and randomly assigned participants to either a growth mindset or a fixed mindset of health condition. In both studies, we measured participants’ mindsets of health, expectancy-value beliefs, healthy eating intentions, past eating habits and demographics.

In Study 1, stronger growth mindsets of health predicted …

Successful Weight Loss Initiation And Maintenance Among Adolescents With Overweight And Obesity: Does Age Matter?, Diana Rancourt, Chad D. Jensen, Kara Mcrae Duraccio, E. Whitney Evans, Rena R. Wing, Elissa Jelalian

Faculty Publications

Background—Treatments for adolescents with overweight/obesity demonstrate mixed success, which may be due to a lack of consideration for developmental changes during this period. Potential developmental differences in weight loss motivations, weight maintenance behaviors, and the role of parents in these efforts were examined in a sample of successful adolescent weight losers.

Methods—Participants enrolled in the Adolescent Weight Control Registry (n = 49) self-reported demographic information and weight history, reasons for weight loss and weight control, weight loss approach and weight maintenance strategies, and perceived parental involvement with weight loss. Associations between age at weight loss initiation and the aforementioned factors …

Efficacy Of Weight Loss Intervention Can Be Predicted Based On Early Alterations Of Fmri Food Cue Reactivity In The Striatum, Petra Hermann, Viktor Gál, István Kóbor, C. Brock Kirwan, Peter Kovacs, Tama Kitkas, Zsuzsanna Lengyel, Eszter Balint, Balázs Varga, Csongor Cseko, Zoltan Vidnyanszky

Faculty Publications

Increased fMRI food cue reactivity in obesity, i.e. higher responses to high- vs. low-calorie food images, is a promising marker of the dysregulated brain reward system underlying enhanced susceptibility to obesogenic environmental cues. Recently, it has also been shown that weight loss interventions might affect fMRI food cue reactivity and that there is a close association between the alteration of cue reactivity and the outcome of the intervention. Here we tested whether fMRI food cue reactivity could be used as a marker of diet-induced early changes of neural processing in the striatum that are predictive of the outcome of the …

From Socioeconomic Disadvantage To Obesity: The Mediating Role Of Psychological Distress And Emotional Eating, Jade Spinosa, Paul Christiansen, Joanne M. Dickson, Valentina Lorenzetti, Charlotte A. Hardman

Research outputs 2014 to 2021

Objective: Lower socioeconomic status is robustly associated with obesity; however, the underpinning psychological mechanisms remain unclear. The current study sought to determine whether the relationship between lower socioeconomic status and obesity is explained by psychological distress and subsequent emotional eating as a coping strategy. It also examined whether psychological resilience plays a protective role in this pathway. Methods: Participants (N = 150) from a range of socioeconomic backgrounds completed questionnaire measures of psychological distress, emotional eating, and resilience. They reported their income and education level as an indicator of socioeconomic status and their height and weight in order to calculate …

Portion Size Influences Intake In Samburu Kenyan People Not Exposed To The Western Obesogenic Environment, Kevin P. Myers, Jeffrey M. Brunstrom, Peter J. Rogers, Jon D. Holtzman

Faculty Journal Articles

For people in the modernized food environment, external factors like food variety, palatability, and ubiquitous learned cues for food availability can overcome internal, homeostatic signals to promote excess intake. Portion size is one such external cue; people typically consume more when served more, often without awareness. Though susceptibility to external cues may be attributed to the modernized, cue-saturated environment, there is little research on people living outside that context, or with distinctly different food norms. We studied a sample of Samburu people in rural Kenya who maintain a traditional, semi-nomadic pastoralist lifestyle, eat a very limited diet, and face …

A Weight–Related Growth Mindset Increases Negative Attitudes Towards Obese People, Nic Hooper, Alison Crumpton, Michael D. Robinson, Brian P. Meier

Psychology Faculty Publications

In implicit personality theory, people with entity views or a fixed mindset perceive characteristics (e.g., intelligence) as uncontrollable, whereas people with incremental views or a growth mindset perceive characteristics as controllable. In addition to other benefits, the literature sometimes suggests that having a growth mindset will protect against prejudice, which the current two studies examine in terms of negative attitudes towards obese people. Participants (total N = 501) were randomly assigned to complete a questionnaire assessing attitudes towards an obese or non-obese person and a self-theory questionnaire also assessed ideas about body weight. People with a growth mindset, and not …

Should Patients With Diabetes Be Encouraged To Integrate Social Media Into Their Care Plan?, Arun R. Nelakurthi, Angela Marinilli Pinto, Curtiss B. Cook, Lynne Jones, Mary Boyle, Jieping Ye, Theodoros Lappas, Jingrui He

Publications and Research

AIM: To evaluate the use of social media of individuals with diabetes mellitus (DM).

MATERIALS & METHODS: Both web-based and in-clinic surveys were collected from individuals with DM. Descriptive and correlation analyses were employed to evaluate respondents' diabetes-specific social networking site behaviors.

RESULTS: Forty-five patients with DM completed the web-based survey and 167, the clinic-based survey, of whom only 40 visited diabetes-specific social networking sites. Analysis of online survey data indicated that self-reported adherence to lifestyle recommendations was significantly correlated (p < 0.01) with visiting the sites. Clinic-based survey data found that patients who reported using DM-specific web sites monitored home glucose values more often and had better compliance with insulin administration (both p < 0.05) compared with nonusers.

CONCLUSION: This study provides insight into why individuals visit DM-specific social networking sites. Certain self-management behaviors may improve as …

Results: At baseline, all FCCH met the minimum childcare standards for fifty-four of fifty-six practices …

The Role Of Craving In Emotional And Uncontrolled Eating, Christina L. Verzijl, Erica Ahlich, Robert C. Schlauch, Diana Rancourt

Psychology Faculty Publications

This study presents a novel application of the cognitive processing model of alcohol craving (CPMA) from the addictions field to the role of food craving in the well-established restrained eating–overeating relationship associated with binge eating disorder (BED). A community sample (N = 1058, ages 18-66) completed an online survey assessing four core domains: restrained eating, trait food craving, uncontrolled eating, and emotional eating. In accordance with the CPMA, food craving emerged as a significant indirect effect of the association between restrained eating and both uncontrolled and emotional eating. Gender did not significantly moderate any direct or indirect associations, suggesting that …

Self-Stigma And Weight Loss: The Impact Of Fear Of Being Stigmatized, Jason Lillis, J. G. Thomas, Michael E. Levin, R. R. Wing

Psychology Faculty Publications

The current study sought to examine whether two facets of weight self-stigma (fear of enacted stigma and self-devaluation) were associated with weight change and treatment engagement for 188 individuals participating in a 3-month online weight loss program. Fear of enacted stigma predicted less weight loss 3-months later after controlling for demographics, eating problems, and psychological symptoms. Self-devaluation did not predict weight loss. Neither weight self-stigma variable predicted engagement in the online program. These results add to the literature indicating the negative effects of weight self-stigma while highlighting the central role of fear of being stigmatized by others in this process.

Providers Perspectives On Self-Regulation Impact Their Use Of Responsive Feeding Practices In Child Care, Dipti A. Dev, Katherine E. Speirs, Natalie A. Williams, Samantha Ramsay, Brent A. Mcbride, Holly Hatton-Bowers

Department of Child, Youth, and Family Studies: Faculty Publications

Supporting children's self-regulation in eating through caregivers' practice of responsive feeding is paramount to obesity prevention, and while much attention has been given to supporting children's selfregulation in eating through parents' responsive feeding practices in the home setting, little attention has been given to this issue in childcare settings. This qualitative study examines childcare providers' perspectives on using responsive feeding practices with young children (2–5 years). Individual semistructured interviews were conducted with providers until saturation was reached. Data was analyzed using thematic analysis. The final sample included 18 providers who were employed full-time in Head Start or state-licensed center-based childcare …
